COMBINED INCUBATOR AND BROODER.

SPECIFICATION forming part of Letters Patent No. 502,900, dated August 8, 1893.

Application filed April 17,1893.

Be it known that I, JAMES W. ATKINSON, a citizen of the United States, residing at San Jos, Santa Clara county, State of California, have invented an Improvement in a Combined Incubator and Brooder; and I hereby declare the following to be a full, clear, and exact do- My invention relates to that class of incubators in which the upper portion of the frame is formed into a brooding chamber which derives its necessary warmth from the heater of the incubator.

My invention consists in the novel construction and arrangement of the brooding chamber, and in connection therewith of the removable heater which serves the double purpose of furnishing the required heat for hatching the eggs and the necessary warmth for the hatched chicks.

The object of my invention is to provide a simple, compact and effective brooder in direct and intimate connection with the incubator, and so arrangedas to permit of the ready removal ofthe heater."

Referring to the accompanying drawings for a more complete explanation of my invention,-Figure 1 is a perspective view of my combined incubator. and brooder. Fig. 2 is a vertical section on the line Ii-fa? of Fig. 4. Fig. 3 is a vertical section onthe line y-y yy of Fig. 4,. Fig. A is a horizontal section on the line zz of Fig. 3. i v

A is the frame of the incubator, having egg drawers B, accessible through doors a. in the front. These drawers are seated in the lower portion of an inside case 0, and directly above them, in the upper portion of the case, is the heater D, which consists of a water containing vessel, the metal top and bottom' of .which are exposed, to form a good conductor of heat. Through the center of this heater passes a drum (1 having a number of heat tubes d. extending through it andopen below to the action of the fiameand the passage. of. the products of combustion from the lamp E. .Opening downwardly from the'heaterD are pipes 61 which enter the water space of the drum 01 below. With one of these pipes a draw off faucet F is connected, said faucet passing in through the front wall of the frame A, and

being screwed into pipe d wherebyit can be Serial No. 470,723. (No model.)

removed when necessary as I shall presently explain.

From the water space of drum d, in the upuary 19, 1892. In the present instance,how-

ever, it, must be noted that the whole heater consisting of the water vessel, and its attached drum and pipes, is so placed within frame A, that it can be readily removed therefrom and replaced, a result which is made possible upon the unscrewing of faucet F, by the arrangement of the brooder, which I shall now describe.

The lid or cover G of frame A is a chambered one and constitutes the brooder. It is hinged at g, Fig. 3, to the frame, and is adapted to be thrown open, to expose the whole top of the frame or to be closed down over it, in which latter position it is secured by latches g. The lid G, which is somewhat like the compartment cover ofa trunk in general shape, has two separatedcross partitions H, betweeneach of which and the adjacent end of the lid is formed a brooding. chamber I, having a suitable bottom,.such, for example, as the wire cloth 2' here shown; though thin boards or other material may be used according to the amount of bottom heat which it may be desired-to receive from the top plate of the heater which lies directly below said bottoms.

Through the space between the cross partitions H, passes the ohiinney'flue or Outlet J, the lower end of which fits over the top of drum d and thence extends upwardly through the lid G and has a, controlling damper j on its top. Between the cross, partitions H are secured horizontal partitions h which form below them the fresh airlheating chambers h.

in direct communication with and lying immediately above the top plate of heater D. These chambers have a communication front and rear through passages 72? with the outer air, and they are also connected by the pipes or passages K with the upper portions of the brooding chambers. I, said pipes opening through the partitions h and H, and being adjacent to the chimney flue J. Issuing from the lower portions of the opposite walls of the brooding chambers are the outlet pipes L. .In the front walls of the brooding chambers are the glazed openings 11, in their back walls the openings 1' for the chicks, said openings being controlled by gates 6 and in the tops of the brooding chambers front and rear are the hinged flaps i by which access is had to said chambers for the insertion and removal of:

the chicks.

M is an outer cage adapted to be removably connected, as by means of the hooks m,

with the back of the brooder, and into this the chicks may pass from the brooder chambers through openings '6 The use of this combined incubator and brooder is as follows :The eggs are placed in 5 the drawers B and subjected to heat in the usual manner until the chicks are hatched. 1

The newly hatched chicks are then placed in the brooding chambers I, by opening the top flaps i. The lid Gbeing closed down on frame 1 A, the brooding chambers I receive warmth A portion of 1 from the underlying heater.

in through passages 77. and collect pure fresh air in chambers h and to heat this fresh air from the top plate of the heater. chambers, the heated fresh air will pass through the pipes K into the brooding chambers I. The foul air will pass out through outlet pipes L. Thus a constant supply and circulation of pure fresh heated air are maintained in the brooding chambers and upon this depends the main success of the raising of artificially hatched chicks. The heater thus serves the double purpose of hatching the eggs and properly warming the brooder. The lights 2" are placed in front to attract and induce the chicks to return to the brooding chambers at night. This construction of the brooder, forming it in a hinged or removable lid or cover for the incubator serves also, as

before intimated, the purpose of permitting the ready removal of the entire heater from the top of the frame A. This is of importance, in that it enables the operator to readily take out his heater for necessary repair of leaks, and other repairs, without having to dismember or tear to pieces the frame, and to this end the heater is fitted and supported loosely in its seat, whereby upon throwing back the lid G, it may be removed by simply lifting it out.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an incubator having a heater, a brooding chamber and a passage contiguous and exposed to said heater and communicating From these r with said brooding chamber and with the outer air, whereby fresh air is heated and supplied to the brooding chamber, substantially as herein described.

2.
